Docker: Best Practices and Gotchas

Hey everyone,

I've been working with Docker for the past few months and wanted to share some best practices I've learned, as well as ask for your insights on a few challenges I'm facing.

• Always pin your base images to a specific tag.
• Leverage multi-stage builds to keep images lean.
• Use .dockerignore to exclude unnecessary files.

One issue I'm encountering is occasional container startup delays due to DNS resolution. Has anyone experienced this? Any tips?

Looking forward to the discussion!
